random numbers with gamma distribution [message #13427]

Dear All

I'm trying to generate a random series that has a gamma distribution, using
the randomu() function with the gamma keyword. The online help says to set
gamma to an integer > 0. WHY DOES IT HAVE TO BE AN INTEGER? The gamma
distribution is in fact defined for all gamma > 0, not just integers.
I want to set gamma=0.5, which currently fails as it converts it to the
integer 0, which is not > 0, and so it fails.

Is this a bug, and is there any work-around?

Cheers

Tim
